ch may be ligated), are the cavernous sinus andthe carotid artery. The extirpation of the ganglion is followed not only by sensory changes, butalso by a unilateral paralysis of the muscles of mastication, since the small motor root in intimaterelation with the ganglion is also removed. Unpleasant symptoms of cerebral compression arenot infrequently observed after the operation. The relations of the nerves in the middle cranial fossa to the cavernous sinus and to theinternal carotid artery are best shown by a frontal section (see Fig. n). The abducent nerve lies upon the internal carotid within the sinus, while the illustrationdistinctly shows the oculomotor, the trochlear, and the first and second divisions (ophthalmic andsuperior maxillary) of the trifacial within the wall of the sinus. Fractures or caries of the base of the skull may involve one or more of the cranial nerves, andthe symptoms produced by the affected nerve may furnish conclusions as to the site of the lesion.

Tumors situatedat the base of the skull may press upon the nerves having a subdural or an intradural course andconsequently lead to more or less severe pressure-symptoms dependent upon the particular nerveaffected. Under certain circumstances olfactory or visual disturbances may point to the presence ofa tumor in the anterior cranial fossa; symptoms of pressure upon the semilunar ganglion anddisturbances of the muscles of the eye may likewise indicate a growth in the middle cranial fossa.If the trunk of the trifacial is pressed upon before it perforates the dura, and if the facial andh
